060B-LIMEM

MON 60 subfunction LIMEM = 60B = 0x30 = 48 decimal. NPL purpose (authoritative, 5P-P2-MON60.NPL): LIST MEMORY CONFIGURATION, server handler 5NOPAR.

All addresses OCTAL, ND-100 word addresses, BANK 1, base 0. Source: SINTRAN/ND500/nd-500-mon/nd-500-mon-j04.prog.asm

60B yaml client name = LIMEM. This is the MEMORY-CONFIGURATION command (INDEX.md 2.1).

Parameter block (PROVEN stores)

Slot	Store	Value
,X 6	135531 STA ,X 6	parameter 1 = &(B-164) = buffer to receive the memory-configuration list

Gateway convention (prog.md sec 4.4): LDX ,B -176 sets X = stack top; STx ,X 6/7/10 are MON 60 parameters 1/2/3.

What it does

1. Sets B-127 := -1 (a sentinel), then passes &(B-164) as the receive buffer. (135524-135531)
2. Issues MON 60 LIMEM to list the ND-500 memory configuration. (135532)
3. On error LEAVEs with the error code (177327); on success falls through to process the returned list.

Unknown / inferred

• PROVEN: param 1 = &(B-164) (135531).
• INFERRED (semantic): B-164 receives a memory-configuration list; the SAA -1/B-127 sentinel role was not carved.
• PROVEN (role): 177327 = LEAVE-with-value (compiler runtime, prog.md sec 4.3).
• INFERRED: LIST MEMORY CONFIGURATION purpose from SUBFUNCTION-TABLE.md; thunk SAA 60 PROVEN.
